Earth’s magnetic field could flip within a human lifetime

Geologists have known for quite a while that the Earth’s magnetic field has flipped many times throughout the planet’s history. Its dipole magnetic field, like that of a bar magnet maintains the same intensity, but for unknown reason(s), it sometimes becomes weaker and changes polarity. Now, a new study has showed that this phenomenon could happen much faster than previously believed – even in a few decades.

Earth’s magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth’s interior to where it meets the solar wind, a stream of charged particles emanating from the Sun. Because the magnetic field is generated by a geodynamo (the motion of molten iron alloys in its outer core), the field intensity changes in time. As you probably know, the geographic North Pole and the magnetic North Pole don’t coincide – they vary significantly, as the magnetic poles wander on the surface of the planet. These reversals of the geomagnetic poles leave a record in rocks which can be used by geophysicists to trace the magnetic reversals of the past. We know for quite some time that magnetic pole reversal is a common phenomenon, even though we don’t know exactly why it happens.

In simulations of planetary dynamos, reversals often emerge spontaneously from the underlying dynamics; also, global field reversals at irregular intervals have also been observed in the laboratory liquid metal experiment VKS2. However, some scientists believe that geomagnetic reversals are not spontaneous processes but rather are triggered by external events that directly disrupt the flow in the Earth’s core. Should this be the case, the cause is likely an inside, tectonic phenomenon.


The ‘north pole’ — that is, the direction of magnetic north — was reversed a million years ago. This map shows how, starting about 789,000 years ago, the north pole wandered around Antarctica for several thousand years before flipping 786,000 years ago to the orientation we know today, with the pole somewhere in the Arctic.

A new study conducted by scientists from Italy, France, Columbia University and the University of California, Berkeley, demonstrated that the last magnetic reversal 786,000 years ago actually happened very quickly, in less than 100 years. If this is true, then there is no reason why this couldn’t happen again.


“It’s amazing how rapidly we see that reversal,” said UC Berkeley graduate student Courtney Sprain. “The paleomagnetic data are very well done. This is one of the best records we have so far of what happens during a reversal and how quickly these reversals can happen.”

Many geophysicists believe that we are due for another magnetic pole reversal this millennium because the Earth’s magnetic field is decreasing 10 times faster than normal, and this new evidence shows just how quickly that could happen. There are no catastrophic events associated with this reversal, though it will likely affect electrical grids and perhaps even cancer rates.

The main problem would be the electrical grid – a quick reversal, on the time scale of a few decades would wreak havoc on our modern economy, so it’s crucial that we understand more about this phenomenon. Furthermore, just because we haven’t discovered any biological catastrophes doesn’t mean that there won’t be any at all. The danger to life would be even greater if flips were preceded by long periods of unstable magnetic behavior.

I find it amazing we may well be alive when it happens. It is really boogie-ing around these days.

Gives the nibiru-heads something to get excited about at least

Same as always.

I have been observing the pole shift since 1970 or so when I began to fly. Runways are identified by their magnetic heading. Over the years the frequency of runways that had to be re-designated due to their magnetic heading changing has increased.

BTW, I thought that was a great article when I read it a couple of days ago. Interesting.....

I've pretty much heard the same thing fos.......
